Hello IJ-list,

is there any way to apply the draw/paint tools on 32-bit (float) images in a useful way? For example, by picking a particular (float) value with the pipette, select a ROI and then fill the region with exactly that value?

It appears that the pipette picks the displayed (lookup) color for the selected pixel but it is not obvious how the corresponding draw/fill value is specified - it is generally not the float value of the selected pixel.

Thanks much for any hints -

Wilhelm
